Question

if the amplitude increases by 6 times, by how many times will the loudness increases?

Answer 1

Answer:

36 times

Explanation

The loudness of a sound is directly proportional to the square of the amplitude.

So, if amplitude increases by 6 times, then, the loudness increases by 6^{2} times, which is 36.

Hope you understood.

Answer 2

Answer:

amplitude increases by 6 times

the loudness increases by 6² =36 times
